message undeliverable. please help

[rkde]

hello.

HELP ME!

I have done a search for this but it comes back with stuff I have tried so here we go.

When I send a text I get a message back saying "Message undeliverable. make sure the text message address was entered correctly and try again"

So far I have checked the service centre and that is right, then I checked the area code and that is right.
When I put my phone near a speaker I can hear it sending but it has been like this for two days!

Any ideas what this could be?

Oh I have done a soft and hard reset and no change, I am an O2 and have done nothing to this phone for about a month now so no reason why it should not send texts. I can recieve calls, mms, and phone calls to include all GPRS data.

thanks

ok its sorted.

But I am going to leave something here to help others.

If you have the same problem and you are with o2 then what you need to do is check you area code in the contacts this is under options. next check your account service number if this is all correct...

have you had your number changed from another account? if so then o2 have not changed your account properly and you have been banned from the contract service number, try using the pay as you go service number.

hope this helps
